Protection classes

The Protection Class specifies how the lighting is protected from electric shock (short-circuit) (IEC 61140:2001 + DIN EN 61140:2002). The attribution can be done with roman numbers or with icons. The meanings are:

Lightings of Protection Class ILightings of Protection Class I Operation insulation and protection earthing of all touchable and conductive parts. Protection Class I is not marked with a symbol. The lighting is determined to a connection with a protective conductor which is labelled with the appropriate test symbol.

Lightings of Protection Class IIIOperation on and with protection voltage and small voltage (max. 50V). Protection Class III characterize lightings that are determined for an operation with a protection voltage (maximum 50 Volt).

The mechanical, thermic and technical safety requirements on lightings are described in detail in the International respectively the European Standards.

Decisive is the regulation EN IEC 598 (Luminaires – General requirements and tests). The conformity to this regulation guarantees that the lightings are constructed in a such a way as not to endanger people, domestic animals and goods, provided that they are installed, tended and used appropriate.
